Grigor Dimitrov has drafted in former world number one Andre Agassi to help out with coaching at the Paris Masters. It will be the second time the pair have worked together after they were seen practising at Georgia Tech University in Atlanta in July.
Dimitrov has drafted in Agassi, who will work alongside full-time coach Dani Vallverdu, to try and bring some consistency back to his game after a tough 2018 campaign.
The Bulgarian won four titles in 2017 but has only made it through to one final this year when he lost to Roger Federer in Rotterdam.
The 27-year-old started out the season ranked number three in the world but has slipped to tenth in the rankings ahead of the French capital event.
